Let me explain. I lost several chicks in my new "flock" before realizing that they had mites. I never knew to check for such a thing, especially in chicks who had never been out of doors. The last chick that died over a week ago was covered in mites, and when I looked at the others, they were covered in mites, too. I am assuming that is what killed them. I treated them, a little over a week ago, very carefully, and their boxes, with sevin dust. I have checked them every day for mites, and the mites are gone. However, before discovering the mites, I had noticed some blood in some of the feces of the chicks. I was thinking coccidiosis (but they had been fed on medicated starter) or maybe necrotic enteritis. So, I treated them with antibiotics for a few days, but I still lost a couple of chicks after that. I have been giving some vitamin/electrolyte mixed in with their water, not every day but about every other day since the treatment. However, I continue to see some blood in some of their feces and in the last couple of days, I have found some bloody spots (more like splotches) in their boxes that are not in the feces. I have examined the birds carefully--no pecking injuries or anything like that. Would they still be experiencing some health problems from the mite infestation? A couple of the birds seem to have stunted growth, possibly, as a result of the mite infestation. I have spent so much time on the internet trying to figure this out. I want to integrate these birds in my henhouse outside in a couple of weeks with my other chickens, but I am afraid to unless I figure this out. Is blood in the stool of chickens ever normal? Also, please let me know if any of you have any idea as to what is going on with my birds. They all look (except the two with stunted growth) and act normal. They are all eating and drinking normally. Also, if anyone has any idea as to how to properly mix the Durvet brand of vitamin/electrolyte mix with water in chick waterers, please let me know. I have been guessing/estimating so far. Should I continue to give them the vitamins/electrolyte? Other than that they are just being given medicated starter/grower and water. Any input will be greatly appreciated. I'm sorry this explanation is SO long. I thought this was all important info.
